Delivery of highly electrically-efficient engines
Orgaworld, since 2007 part of the Shanks Group, has establishments in the cities of Amsterdam, Lelystad and Drachten. The company develops, realises and operates plants and installations for processing organic waste. One of these plants is the Biocel GFT (organic waste) fermentation plant in Lelystad. The organic waste is fermented in one of the fourteen gas-tight reactors. During the fermentation process, biogas is created. This biogas is used to generate electricity and heat using a combined heat and power plant (CHP).
Why MAN Rollo was chosen
The Biocel fermentation plant was built in Lelystad in 1996. This means that the existing engines are now 20 years old. Orgaworld decided to renovate the location and the overhaul of the CHPs was included in the scope of the project. “We made an extensive inventory of the wishes, including the size and efficiency of the engines,” were the opening words of Harald Koehorst, Operational Manager at Orgaworld and responsible for the locations in Amsterdam, Lelystad and Drachten. The next step for the project team was to draw up a tender document. MAN Rollo and various other companies responded to this document. After drawing up the short list and visiting various reference projects, it was decided to award the contract to MAN Rollo.
“The initial meeting with MAN Rollo left a positive impression. The company is strong in the area of gas engines up to 500 kW and has a good reputation and strong position in the biogas sector. The price was good, the engines are highly electrically efficient and the feeling was good – not an unimportant factor.” Another reason to choose MAN Rollo is that the company meets the requirements of a number of Flevoland municipalities. This is because these municipalities operate a policy that stipulates that an organic waste processor must produce a certain amount of electricity from the waste. Therefore, it is essential that the conversion of biogas to electricity is highly efficient. “From this viewpoint it was mandatory to work with a party that could meet this requirement. The contract for supplying two biogas CHPs for the Biocel fermentation plant in Lelystad was therefore awarded to MAN Rollo. Each 400-kWe CHP is installed in a large, sound-insulated container (7.5 x 3 metres). The MAN engines have a higher electrical efficiency than the former engines”, says Harald.
From delivery and commissioning to long-term full service
“The decision to cooperate with MAN Rollo was taken unanimously by the project team. After signing the agreement, the project was handed over to the Operations department. It is now up to my department to get the maximum return from the engines. Orgaworld supplies electricity to the gird and the heat is used in the company itself.
MAN Rollo installed the engines in November 2015; they have run satisfactorily from December. The uptime of the CHPs is very high, in part due to the short lines of communication and the rapid response time of MAN Rollo’s service department. The fault-clearing service is well staffed, and can be contacted and is available 24/7. MAN Rollo arranged the delivery, installation and commissioning. In addition, Orgaworld entered into a full-service contract with MAN Rollo for a period of 10 years.
Every project has some remaining issues. So has this project, but I am confident that these last ones will be correctly resolved. We are happy that we chose MAN Rollo. We even asked MAN Rollo to think about the overhaul of the engines that are currently running in Amsterdam.”
